Text logs made by an employee of an organisation which state simple text and offer no proof of filesend or of the file's contents are meaningless.
With that line of thought any text log of any kind would be meaningless, but we arn't discussing the legal aspect of it are we. Based on what I mentioned before about "Hollywood and the record companies" what proof do they need to make sure that fileswapping becomes regulated or restricted to uncopyrighted files? Absolutely nothing, especially when they see fit to take the law into their own hands.
It's no different to, for example, someone hacking my network. If I assume it is a particular person then I won't bother asking questions or wastintg police time with it. I would choose between owning them or ignoring it. Do I need actual proof or just a text message from my firewall to make that choice?
Looking at things from a legal aspect, always remember that most of the hoohar comes from the US (RIAA) and US based record companies. In the US you can sue your next door neighbour for poking their tongue at you or for letting their dog poop on your front lawn. What evidence do you need? Maybe a pic of the grogan gently nestled on your grass. Who knows? Courts have been known to find guilt on lesser evidence. It's only your job to prove beyond a reasonable doubt not beyond any doubt. It might suck but it's democracy.
